Those found and used by kmail, LibreOffice, > kleopatra for digital signing. openpgp certificates are not specified to be used for pdf files. For that we need CMS - https://en.wikipedia.org/wiki/Cryptographic_Message_Syntax - and CAdES - https://en.wikipedia.org/wiki/CAdES_(computing) - according to the pdf specification section 12.8. I have not seen anyone specifying CMS with openpgp keys, only with x509 certificates. -- You are receiving this mail because: You are the assignee for the bug.
